Seriously I don't know why they would make an expansion pack to Cossacks in the first place, unless they where adding sound effects. Why sound effects? Well, because Cossacks lack a lot of sound effects and had script, mainly because of this it makes the game a little less fun in other categories. Basically this expansion pack adds 5 campaigns, new maps, 2 new nations, a couple of new ships, a few historical battles, a new multiplayer mode, new orders for troops, and improved AI. These things do improve the gameplay but the gameplay still isn't as fun because it is scripted, but these are great improvements to the game. The storyline is still the same great storyline just for different countries. The replay value is a little bit better with the new multiplayer mode online. The graphics are a little bit enhanced. The environments are beautiful and amazing. The game is still scripted and it is very annoying to play a scripted game, trust me. This expansion pack does improve the game but it still need to get the scripted gameplay removed and it would be an even better game.
